After a power outage this weekend, when HASS came back up I lost all automations related to my Sonoff Orb 4-Way smart switch, and one of my GE 800 Z-Wave switches no longer responds, though it still works manually pressing the switch.
I’ve re-entered the automations, but I can’t get the switch so come back to home assistant. Is the only path forward deleting, resetting it, and re-adding it? I’ve never had this happen. I’m not 100% sure the power outage caused the issue. I updated the core this weekend also. I think that was before the outage, but I hadn’t checked to see if everything was there after the update/before the outage.
Have you tried re-interviewing the devices as a first step?
I was looking for that. Your note jogged my memory and I was able to find it. Strangely, the device was saying that it was being interviewed. I’ve rebooted home assistant again. When I tried to reinterview, it fails immediately. I see the following in the log:

Strange that the physical switch still works though.
I’ve had occasional problems with z-wave devices that stop responding. The fix has required power cycling them at the breaker box, then re-interviewing and rebuilding routes. Hope that works in your case.
